My wifes berlingo has been having trouble.
I had air in the fuel to the inj pump caused by a bad priming pump, fitting a new filter housing has sorted this, now the car drives and you can accelerate full throttle no problem.
However at mid throttle accelerating the engine smokes and the engine power sort of pulses, as though you were pressing and releasing the throttle pedal to the floor.
I noticed that the exhaust connection from the front box to the inlet of the cat is leaking, theres carbon around this area, the front box was changed in dec so the mrs had taken it back to that garage this am.
Would a bad exhaust connection cause the engine to surge?, I know it could be the cause of the smoke, these problems started when the new exhaust was fitted.
I was thinking maybe the crank sensor was bad, however I have a obd2 interface and plugged it in last night, I get 1115 rpm which tells me the crank sensor is ok as this is where the rpm calc comes from, its also shows me engine loading which comes from the pump, and engine coolant temp, so electrically it seems ok.
